Kristina Rose leaves no doubt after 3 1/2 hours of prime hardcore footage that she is one exceptionally dirty girl. Director Sam No captures every inch of Kristina's filthy antics with gonzo expertise, and with each progressive scene, Kristina just seems to get dirtier and dirtier.

Kristina is featured in every tease and every scene throughout the disc, from a poolside, MTV-style striptease with Tori Black to her first on-camera anal performance (with James Deen) and on to a six-man blowbang that leaves Kristina a dirty, filthy mess by the end. But things get particularly dirty when the blowbangers start dropping loads on Kristina's face. She presses a giant vibrator against her clit and comes as they do.

Kristina gets off on being dirty. And she brings a primal fury to this disc that makes these scenes stand out in a big way. Following the poolside tease with Black, Kristina and Tori team up with Mark Ashley for some aggressive raunch that features a good bit of hair pulling and faces stuffed into sofa cushions.

The intensity never falters all the way through to the end during a showstopper between Kristina, Rebeca Linares and Michael Stefano. Both girls take it in the ass, but more important is the genuine carnal passion all three performers put into the scene. That kind of passion is something of an intangible, and it's rare. But Kristina manages to exude it throughout Dirty Girl, delivering one exceptional performance after another.

If this disc is any indication, 2009 will be a noteworthy year for Kristina Rose.
